Deciding between a pool house and an ADU (Accessory Dwelling Unit) hinges on your goals.
Both structures offer additional space, but it is the purpose of that space that sets them apart (both from a legal and practical point of view).
Understanding these differences helps ensure you make the best choice for your property.
What Is an ADU?
An ADU (Accessory Dwelling Unit) is a fully functional secondary dwelling unit on the same lot as a primary residence.
These units are designed for full-time living, equipped with kitchens, bathrooms, and bedrooms.
ADUs are versatile, often used as rental units, guest accommodations, or independent living spaces for family members.
What Is a Pool House?
A pool house is a small ‘structure’ near to or next to a pool- these are commonly used to store pool equipment.
They can also be used as a changing room or simply as a place to relax. Some fancy pool houses may have kitchens or bathrooms as well, but the key difference here is that they are not livable spaces like an ADU.
Differences Between a Pool House and ADU
Pool houses and ADUs are sometimes referred to as the same thing, but there are some very key differences that set them apart.
ADUs Are Livable Spaces
ADUs are livable spaces, meaning they contain everything you would need to live like kitchens, bathrooms, bedrooms, etc.
Pool houses are literally just small buildings or structures next to pools used for basic things like changing, storing equipment, and so on.
This fundamental difference impacts not only the functionality but also the regulations governing these structures.
Setback and Building Requirements
Because ADUs are considered livable spaces, they must meet stricter building codes and setback requirements.
These regulations include ensuring proper insulation, fire safety, and adequate plumbing and electrical systems.
On the other hand, pool houses, classified as detached non-habitable accessory buildings, face fewer restrictions. This classification often allows for more flexible placement on the property but limits their usage to non-residential purposes.
For example, depending on the lot, you can typically build a larger non-habitable accessory space than an ADU, as ADUs are capped at 1,200 sq ft, while non-habitable accessory spaces depend on the lot size (read more about that here).
Functionality and Use
ADUs offer a broad range of uses, from generating rental income to providing a comfortable living space for extended family members.
They’re obviously much more functional than pool houses, and this is by design.
Some pool houses can be quite useful though, especially those that have extra features like showers or a barbecue area.
Additional Costs and Maintenance Considerations
There’s no doubt that an ADU is going to be a hell of a lot more expensive to build and maintain, but that goes without saying for a fully independent living space.
This is just the price to pay for a living space that contributes to property value and can be rented out if you choose,
In comparison, pool houses are child’s play. This again makes sense for an addition that is primarily used in convenience to help you have more fun by the pool
Can You Build an ADU Next to a Pool? (And Vice Versa)
Yes, you can build an ADU next to a pool, and you can also place a pool next to an existing ADU.
However, careful consideration is needed to ensure both structures comply with local zoning laws and setback requirements.
For instance, safety regulations might require barriers or specific distances between the pool and the ADU to prevent accidents.
Thoughtful planning is essential to ensure that the layout of your property is both functional and aesthetically pleasing.
What Is a ‘Pool House ADU’?
The term “pool house ADU” is often misleading, and one of the reasons why so many people get confused with ADUs and pool houses.
A so-called ‘pool house ADU’ is simply an ADU built near to a pool, that’s it.
Unlike a typical pool house, a “pool house ADU” is a fully livable space designed with all the amenities of a home, including a kitchen, bathroom, and bedroom.
So That’s It
Pool houses and ADUs are very different, even though they are sometimes called the same thing.
ADUs offer significant flexibility and value, especially if you plan to generate rental income or need additional living space.
Pool houses are great for making the most out of your poolside space, but the uses are naturally more limited than an ADU.
The choice should be very straightforward once you understand exactly what each type of building is used for.
